In a new resolution on the European Union’s (EU) net-zero strategy, the European Parliament once again acknowledged the political urgency for legislation on what has, to date, been Europe’s climate blind spot: methane emissions. This vote on March 14, is the fourth significant development in the space of the last six months, raising expectations that the EU is finally embracing a major opportunity to better characterize emissions of methane and take action to unlock cost-effective mitigation.
Methane is a short-lived climate pollutant. Increases of methane in the atmosphere from human activity account for more than 25 percent of the warming we currently experience. According to the Intergovernmental Panel on Climate Change (IPCC), over a 20 year period, methane has a global warming potential (GWP) up to 87 times higher than CO2. While methane breaks down in a decade, carbon dioxide sticks around for more than a century. To avert climate catastrophe in the near term and long term, we must reduce both.
